- Methods of manufacturing or preparing the composition are detailed.
What are the key claims of JP2005519909?
The claims generally can be classified as follows:
Independent Claims:
- Encompass a pharmaceutical composition with a specified active ingredient and a carrier or excipient enhancing absorption.
- A method of preparing such compositions involving certain steps or process conditions.
- Delivery systems that include specific routes (oral, injectable, transdermal) or device features.
Dependent Claims:
- Narrow the scope to particular dosages, ratios of ingredients, or specific formulations.
- Claim stability, shelf-life, or release profiles.
- Claim apparatus or device components, e.g., patches, capsules, or tablets.
Example Claim (hypothetical):
"A pharmaceutical composition comprising [active ingredient], and [excipients], wherein the composition exhibits enhanced bioavailability compared to prior art."
The actual language includes technical terms related to pharmaceutics, such as "buffer system," "controlled release," or "targeted delivery."
